puritanism

The term 'Puritanism' is built upon the 16th-century English word 'Puritan', which originally designated a member of a Protestant group seeking to 'purify' the Church of England of perceived Roman Catholic residues. The core 'purit-' derives from Late Latin puritas (purity, cleanness), which traces back to Latin purus (pure, clean), a word of Proto-Indo-European origin. The suffix '-an' (from Latin -anus) denotes 'one belonging to or concerned with'. The final layer, '-ism', borrowed via Latin from Greek -ismos, transforms the label for the people into the abstract noun for their entire doctrinal system and its characteristic strictness. Thus, the word's logic moves from the ancient concept of purity, through the identity of a reforming group, to the codified set of austere principles they championed.
